Claims.

This invention relates to :a transfer vvalve and more particularly to a valve Yadapted `for attachment to a mobile `water tank such as is commonly used for hauling wat-er toa concrete mixer and for sprinkling concrete that has been laid.

The primary object ofthe invention is to facilitate the loading of the mobile tank, and the `discharge of ,the liquid therefrom.

Another object is to facilitate the Atransfer of the liquid within the tank from one place to another without danger of leakage or loss during the period of transit.

The above and other objects may be attained by lemploying this invention which embodies among its features a transfer valve adapted. to be attached to the discharge port, of a mobile tank comprising a valve body having -a flow chamber extending across one end `which is provided with a port communicating with the tank, said valve body having `an inlet chamber, and a discharge chamber adjacent the opposite end ofthe valve body, said body :also having Ia pump intake chamber disposed between the inlet chamber Iand the ilow chamber and a pump discharge kchamber disposed between the discharge chamber .and the flow chamber, the walls of the pump intake chamber, and of the pump discharge chamber having ports therein which communicate withithe ow chamber and with the inlet chamber and the discharge chamber, and vmeans operable in both the pump intake and the pump discharge chambers selectively to close the respective port there- Other features include a check valve operable to prevent the iiow of -liquid from the ow chamber into the pump discharge chamber 'and a second check valve operable in the inlet chamber to prevent the iiow of liquid through the inlet port thereof.

In the drawings:

Figure 1 isa fragmentary side view of a mobile tank showing this improved valve attached thereto, -certain porti-ons being shown in section to more fully illustrate the details of construction,

Figure 2 is a botttom plan view of the valve,

Figure 3 is :a sectional view through the valve diagrammatically showing it connected to-a pump with the control valve set to -ll the tank,

Figure 4 is 'a view similar to Figure 3 `showing the valves set to prevent the discharge of liquid from the tank,

Figure 5 is a view simi-lar to Figure `3 vlshowing the valves set to discharge liquid from the tank, and

Figure 6 is a'view similar to Figure 3v showing 2 the valves set to pump the liquid from a source other than the tank and discharge it under pressure through the discharge line.

Referring to lthe drawings in detail, a portable or mobile Itank I6 is provided in its bottom wall l I with a discharge Iopening I2 in-to which a bushing I 3 is rltted. This bushing extends downwardly into a tubular member I4 having an attaching ange i5 lwhich is adapted to be welded or otherwise secured tothe under side of the bottom wall I I to form a uid tight joint therewith. Threaded or otherwise connected to the lower extremity of the tubular member yIl! is a nipple I6 which is carried by my improved valve designated generally Il which comprises a rectangular valve body I8 the -top of which is closed .by a solid wall I9 while the bottom open side of the body I8 is closed by :a removable cover plate 20 held in proper position on Ithe valve body I8 by means of attaching screws 2I A suitable sealing gasket 22 .forms a fluid tight joint at the junction of the body I8 and .the cover plate 20. Attached to 4one end of the valve body is a substantially .U- shaped yframe carrying spaced blocks .24 which are provided with internally screw threaded openings 25 for a purpose to ybe more fully hereinafter explained. T-hese internally screw thread- `ed openings 25 are aligned with spaced openings 26 `formed in the bight portion of the U-shaped frame 23 as will be readily understood upon referen-ce to Figure 2.

The body I8 is provi-ded with ya port 21 which communicates 'with the interior of the nipple I 6 and extending transversely of the body I 8 near 4the end having a .por-t 2'I is :a partition wal1 28 forming a flow chamber 29 which extends throughout the entire width thereof. A second transversely extending partition wall 30 is provided in the valve body I8 in spaced rel-ation the partition wall 28 land extending longitudinally of the body between the partition wall 28 and the end oi Ithe body I8 opposite that containing the flow chamber 29 is a partition Wall 3|. It will thus be seen that that portion of the valve ,body I8 between the flow chamber 29 and the opposite end of the body will be `divided into a plurality .chambers 32, 33,34 and 35 respectively hereinafterref-erredto as the inlet chamber, the `pump intake chamber, the pump discharge chamber and the discharge chamber or valve discharge chamber. Formed in the partition wall 3l) is a pair of spaced ports 36 andl3'I which respectively establish communication between the inlet chamber 32 and thelpump intake chamber 33, land the discharge chamber 35 and the pump discharge chamber 34. Aligning with the port 35 and formed in the wall 28 is a port. 38 which establishes communication between the pump intake chamber 33 and the flow chamber 29, and formed in -axial alignment with fthe port 31 in the wall 28 is a port 39 which establishes communication between the rpump discharge chamber 34 and the flow chamber 29.

Threadedly mounted in each of the openings 25 in the blocks 24 are externally screw threaded valve stems 40 and 4|. The outer ends of these stems are provided with hand wheels 42 by which Y the stems may be rotated While the inner ends of the stems enter the chambers 32 and 35 respectively through suitable packing glands 43. These stems extend longitudinally through the chambers 32 and 35 respectively and attached to the innermost end of the valve stem 40 is a valve 44 which is operable within the chamber 33 while the innermost end of the valve stem 4l carries a valve45 which is operable in the chamber 34. The valve stem 4D is of sufficient length and threaded for a'distance sufcient to enable it to close the port 36 or the port 38 as the case may be and the valve stem I4l is likewise of suiicient length and threaded for a distance sufficient to enable it to move the valve 45 into a position to close the port 31 or the port 39.

Extending transversely of the bushing I3 intermediate ts end is a web 45 having an axially arranged internally screw threaded opening 41 for the reception of the threaded end of a valve stem 43 carrying at its inner end a valve 49 while the outer end of the valve stem extends through a suitable packing gland 50 carried by thecover plate 20 and is provided with a hand wheel by means of which the valve 49 may be moved to open or lclose the passage through the bushing I3 and thus prevent the entrance of the liquid into or out of the tank I0 or if the valve is open to permit the liquid to be pumped into the tank or discharged therefrom as the case may be. Carried by the cover plate 20 are downwardly extending inclined threaded sockets 52, 53, 54 and 55 which communicate respectively with the chambers 32, 33, 34 and 35. A suitable check valve' 56 is arranged adjacent the inside of the cover plate 20 to prevent the flow of liquid out of the chamber 32 and into the nipple 52, and a suitable check valve 51 is operable in the chamber 29 to prevent the flow of liquid from the chamber 29 through the port 39 and into the chamber 34.

In operation a suitable liquid supply pipe such as a flexible hose 58 is connected to the socket 52, and a similar flexible hose or other suitable connection 59 is connected to the socket 53 and leads to the intake side of a pump diagrammatically indicated at 60 in Figures 3 to 6 inclusive. The discharge side of the pump is connected through a suitable `conduit 6| to the socket 54, and a discharge pipe 62 is connected to the socket 55 opening into the discharge chamber 35.

Upon setting the valves 44 and 45 into the positions illustrated in Figure 3 and connecting the pipe 53 with a suitable source of water supply, it is obvious that upon operating the pump 60 liquid will be pumped from the pipe 59 through the check valve 56 and into the inlet chamber 32 from whence the liquid passes through the port 35, the pipe 59 and .pump 60 to be discharged through the conduit 6| into the pump discharge chamber l34 from whence it passes through the port 39 and into the flow chamber 29 to be discharged through the port 21 and with the valve 49 in open position, finally into the tank I9. Having filled the tank it is only necessary to turn the stem 40 to move the valve 44 into the position illustrated in Figure 4, disconnect the supply pipe 58 and carry the liquid to the point where it is to be used. The discharge pipe 62 is then lconnected to the socket 55 and upon moving the valve 45 into the position illustrated in the Figure 5 it will be obvious that when the pump is operated, the liquid will be pumped from the tank l0 into the iiow chamber 29 from whence it passed through the port 38 into the pump intake chamber 33. Leaving the pump intake chamber 33 through the conduit 59 the iiuid enters the pump 60 and is discharged therefrom through the conduit 6l into the pump discharge chamber 34. The liquid iiowing through the port 31 enters the discharge chamber 35 and is forced therefrom through the pipe 82 to the concrete mixer or to be sprayed upon the finished or layed concrete. In some instances it may be desirable to connect the pipe 58 directly to a hydrant and thus avoid the necessity of discharging the tank HJ in which event the valves are set into the position illustrated in Figure 6 so that the flow will be through pipe 58 into the inlet chamber 32 and thence through port 36 to the lpump intake chamber 33 from whence the liquid will pass through the conduit 59 to the pump 59 and be discharged through the conduit 6| into the pump discharge chamber 34 from whence it will pass through the port 31 into the discharge chamber 35 to be forced out through the discharge .pipe 62.

It is obvious from the foregoing that by the simple manipulation of the hand wheels 42 which may be conveniently located to be accessible from the rear end of the tank l0, the various different ports of the valves may be readily controlled.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
